JAMES MARK NAUGHTON, OF COLUMBUS, OHIO.

GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 671,1I5, dated April 2, 1901.

Application filed May 7, 1900. Serial No. 15,780. (No modeL V To LZZ whom, it may concern:

Be it known that I, JAMES MARK NAUGH- TON, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Gas-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others'skilled in the art to which it appertains to make and use the same.

This invention aims more especially to provide an improved burner for use in connection with a Welsbach mantle. I-Ieretofore these mantles have been supported or hung ou a metallic rod and in some instances upon a rod of refractory material set centrally in a metallic socket riveted or seated in a gauze tip. In both cases the support after a short time loses its perpendicularity and the mantle drops over and falls to pieces. In cases where groups of mantles are usedin one lamp the trouble is aggravated because of the increased heat.

In the accompanying drawings, Figure `l is a central vertical sectional View of the burner with my improved tip. Fig. 2 is a top plan view of the body of the burner with the mantle and its support removed. Fig. 3 is a top plan view with the improved tip removed. Fig. 4 is an edge view of the pieces out of which the tip is formed.

Like characters of reference in the several views designate corresponding parts.

l designates the body proper, which is of enlarged size or cup shape at its upper end. A bridge 2 subtend's the inner sides of the cup-shaped portion, and extending upwardly from this is a socket portion 3. The interior wall of the cup-shaped portion is made with a shoulder l, and the exterior of the socketed portion is also made with a shoulder 3, the latter located in a horizontal plane above the plane of the shoulder on the cup-shaped. portion to receive the outer and inner coils, respectively, of the burner-tip. It will be noted that these shoulders ila and 3@ are 1ocated at the top of the cup-shaped portion and somewhat above the bridge, so that the latter shall not in any wise impede the flow of gas through all parts of the tip. The socketed portion 3 is shown to be made with a clear opening from end to end through the bridge; but this opening'is enlarged at its upper end and is furnished with a shoulder against which the lower end of the mantlesupporting rod Lis sustained. In event the mantle-supporting rod breaks off close to the upper end of the socket-piece andmit becomes difficult to pick out the fragment with the fingers such fragment can be pushed out with a slender rod or wire inserted from below.

The tip portion ot' the burner is formed of two strips of sheet metal, one corrugated, 5, and the other plain, 5?, as indicated in Fig. 4. These two strips are folded together and then wound or coiled, as seen in Fig. 2. When pieces of proper length are so folded and coiled, they fit compactly in the upper end of the cup-shaped portion of the burner proper, the outer coil resting on the shoulder la andthe inner coil resting ou the shoulder 3a. The corrugated strip in the coils alternates with the plain, and hence numerous passages for the How of the gas are provided. The mantle-supporting rod is formed of burnt clay or other refractory material and does not soften and bend under any heat to which it can be subjected in the kind of lamps to which this invention relates. The socket-piece has its support in the bridge 2, and hence cannot loe affected by any change in the burner-tip. The tip, however, when of the construction shown is not liable to bend or get out of order because of the considerable width of the strips forming it.

It will be understood, of course, that my drawings herewith show one embodiment only of my improvements and that the several parts thereof can be changed to some extent without departing from the scope of my invention. For example, the bridge 2 need not necessarily span entirely the bore of the cup-shaped portion, but can be connected with one side only. Further, the two strips composing the tip are not necessarily wound spirally, but can be folded and bent in any way to form the tip so that it shall iit the end of the cup-shaped portion.

What I claim, and desire to secure by Letters Patent, is-

1. A gas-burner comprising a cup-shaped portion, a bridge standing between the sides thereof, a socket portion extending upwardly IOO from said bridge, and shoulders formed on the interior of the cup-shaped portion and on the exterior of the sooketed portion, substanc-ated in ahorizontal plane above the shoulder of the Cup-shaped portion, substantially as shown.

3. A gas-burner Comprising a Cup-shaped portion,- a shoulder on the interior side thereof, a bridge standing between the sides of said Cup-shaped portion, combined with a removable tip supported at its center on the socket portion and at its rim on the shoulder of the cup-shaped portion, substantially as described.

In testimony whereof I affix my signature Vin presence of two Witnesses.
